Sub scan registration mechanism

After correcting the main scan registration, the sheet passes through the transfer timing roller [2] and the transfer timing sensor [1] detects the leading edge of the sheet.

The rotation speed of the transfer timing roller [2] is adjusted according to the timing the leading edge is detected, to deliver the paper for the belt-to-paper transfer process at the perfect timing.

If the leading edge is detected at a timing that exceeds the adjustment range (+/-4.0mm), the system alerts J080 and stops.
